**Question:** A 45-year-old man is brought to the emergency department after vomiting up frank blood. This has never occurred before and he reports no prior symptoms of nausea, vomiting, or ASA/NSAID use. His past health history is significant for chronic alcoholism. On physical examination, his blood pressure is 94/73 mm Hg, heart rate 110/min, and there are signs of chronic liver disease. He is resuscitated with IV fluids (normal saline) and undergoes urgent endoscopy which reveals the findings shown in Figure below. Which of the following is the most likely diagnosis?

A. Esophagitis
B. Gastritis
C. Diverticulitis
D. Gastrointestinal malignancy

**Correct Answer:** D. Gastrointestinal malignancy

**Core Concept:**

The presented case demonstrates a patient with a history of chronic alcoholism and presenting with hematemesis (vomiting of blood). The clinical scenario is consistent with a gastrointestinal condition as the patient has not experienced similar symptoms before and there is no history of NSAID or ASA use. Chronic alcoholism can cause damage to the gastrointestinal tract, increasing the risk of gastrointestinal malignancies.

**Why the Correct Answer is Right:**

The correct answer is D. Gastrointestinal malignancy because the patient's clinical presentation, history, and endoscopic findings strongly suggest this diagnosis. The patient's history of chronic alcoholism significantly increases the risk of gastrointestinal malignancies, particularly esophageal and gastric cancers. The patient's blood pressure (94/73 mm Hg) and tachycardia (heart rate of 110/min) reflect septic shock due to the underlying malignancy or its complications. The endoscopic findings (not shown in the figure) reveal the presence of blood, indicating active bleeding from the gastrointestinal tract.

**Why Each Wrong Option is Incorrect:**

A. Esophagitis: While alcohol is associated with gastroesophageal reflux disease, the patient has no history of heartburn or reflux symptoms. Additionally, the endoscopic findings reveal active bleeding, not esophagitis.

B. Gastritis: Chronic alcohol consumption can cause gastritis, but the patient's history does not mention any recent viral infection or medication intake (such as ASA or NSAIDs) that could cause acute gastritis. The active bleeding suggests a chronic condition, and the absence of other risk factors for acute gastritis further supports this diagnosis.

C. Diverticulitis: Chronic alcohol consumption is associated with diverticulitis, but the patient's presentation of active bleeding and septic shock indicates a more severe condition. The endoscopic findings reveal active bleeding, not diverticulitis.

D. Gastrointestinal malignancy: Chronic alcohol consumption is a significant risk factor for gastrointestinal malignancies, particularly esophageal and gastric cancers. The patient's history of chronic alcohol consumption and signs of septic shock due to ongoing bleeding suggest a malignant cause. The endoscopic findings reveal active bleeding, which is consistent with a malignant lesion causing the bleeding.

**Clinical Pearls:**

In chronic alcohol consumers, gastrointestinal malign
